X. Top-j)Ki:ssiXG FOR Hay. 



The experiments in the prodnction of hay, by using in rota- 

 tion as top-dressing barnyard mannrc, wood ashes and a mixture 

 of bone meal and muriate of potash, have been conliiuied during 

 the past year in the nine-acre field whore these experiments 

 have been in progress since 1803. The average yield for the 

 entire area this year was at the rate of 5,853 pounds per acre. 

 The yields on the difFcrent materials used in top-dressing were 

 at the following rates per acre : — 



Pounds. 



Barnyard manure, ......... 5,641 



Fine ground bone and niuriate of potash, ..... ti,076 



Wood ashes, 5,523 



The crops this year were lighter than usual, as a consequence, 

 without doubt, of the marked deficiency in rainfall already re- 

 ferred to. The average yields to date luider the different sys- 

 tems of top-dressing have been at the following rates per acre : — 



Pounds. 



Barnyard manure, ......... 6,343 



Wood ashes, 5,789 



Fine ground bone and muriate of i^otash, ..... 6,159 



The average yield of the 9 acres from 1893 to 1910 inclusive 

 has been at the rate of 6,134 pounds ])er acre. The rates of ap- 

 plication per acre are : — 



1. Barnyai'd manure, ....... 8 tons. 



2. Wood ashes, 1 ton. 



Ground bone, (iOO jiounds. 



Muriate of potash, 200 pounds. 



XL WiNTKK V. Spring Application of Manure. 

 The experiments in progress for the ]mrpose of testing the 

 relative* advantages of applying m;inur(> in the Avintor or in the 

 spring were begun in 1899. There are five pairs of plots. In 

 each pair the manure is applied to one plot some time during 

 the M'inter. At the same time sufficient mHnur(> for the other 

 and of the same qualify is placed in a large heap, from which it
